DISPERSAL OF SEEDS AS NEST MATERIAL BY THE CACTUS WREN
Milton, S. J., W. J. Dean, G. H. Kerley, M. T. Hoffman, AND W G. Whitford. DISPERSAL OF SEEDS AS NEST MATERIAL BY THE CACTUS WREN. SOUTHWESTERN NATURALIST 43(4):449-452, (1999).
Cactus wren (Campylorhynchus brunneicapillus) nests from the southern Chihuahuan Desert contained viable seeds of grasses, forbs, and shrubs. The most common plants used as construction material in these nests were Muhlenbergia porteri, Boerhavia spicata, and the alien grass Eragrostis lehmanniana. We suggest that birds are potentially important dispersers of certain types of plants in semiarid rangelands through the use of plants with seeds as nesting material. Implications of this process from rangeland plant dynamics need to be further explored.
